A die-cast heat sink is a type of heat sink manufactured using the die-casting process and is widely used in the electronics, telecommunications and computer industries. Its main function is to help electronic equipment in high load work effectively heat dissipation, to ensure stable operation of the equipment. Compared with the traditional casting process, the die-casting process has higher precision and better heat dissipation performance, so it has become an important choice in the manufacture of modern heat sinks.

What Is Die Casting?

Die casting is a metal casting method in which molten metal is injected into a metal mold under high pressure and cooled to form the desired shape. The process is applicable to light metal alloys such as aluminum, zinc, and copper, and has the advantages of high productivity, high precision, and smooth surfaces. Die casting is usually used in the production of high-precision parts, such as automotive parts, electronic product shells, heat sinks and so on.

The Production Process of Die-casting Heat Sink

Mold design and manufacture: first of all, designers according to the specific requirements of the heat sink, design the corresponding mold. The design accuracy of the mold determines the quality and performance of the heat sink.

Molten metal injection: choose suitable metal material (such as aluminum alloy), heat it to molten state, and then inject the molten metal into the mold through die-casting machine.

Cooling and demolding: After the metal is injected, it is rapidly cooled in the mold to form the desired shape of the heat sink. The cooling time is short and the production efficiency is high.

Post-treatment: The cooled heat sink usually needs to go through deburring, surface treatment and other processes to ensure its quality and appearance.

 Advantages of Die-casting Heat Sink

1. Excellent heat dissipation performance

Die-casting heat sink adopts high thermal conductivity material (such as aluminum alloy), which has excellent thermal conductivity. Through the fins and streamlined structure of fine design, die-casting heat sink can greatly increase the heat dissipation area and thus improve the heat dissipation efficiency.

2. Precise manufacturing process

Die-casting process is characterized by high precision, the production of the heat sink size precision, smooth appearance, can meet the strict requirements of different equipment on the heat sink. Compared with the traditional casting process, die-casting products are more detailed, can effectively reduce the flaws and defects.

3. Fast production and high efficiency

Die casting process of production efficiency is very high, suitable for mass production. This makes the die-casting heat sink can provide high-performance heat dissipation program at a lower cost, widely used in various types of electronic equipment.

4. High degree of design freedom

Because of the precision of die-casting process and complex shape molding ability, heat sink designers can according to the specific needs of the product for diversified design. Whether it is the shape, structure, or the number and layout of cooling fins, all can be flexibly adjusted to improve the heat dissipation effect and aesthetics.
